I would suggest a wether, and if you're not getting a bottle kid, or one that has been raised solo then I'd suggest getting two.
Goats don't generally stink, only bucks. Nubians are good, in my experience they seem to like horses better. You'll want one that is polled or has been disbudded. I raised Nigerian Dwarf goats and disbud all mine as babies. Most dairy breeds will be disbudded.
To bad you're not closer, I currently have the sweetest, most adorable little nigi wether avaliable, and soon may have some mini alpines avaliable.
